Best Answer

The Appalachian Mountains are millions of years older than the Rocky Mountains. Geologists believe the Appalachian Mountains once had active volcanoes because of the types of rocks found but these went extinct long ago. Because of erosion, wind, and time, the Appalachian Mountains are now more rounded and less in height.

Why are the Rocky Mountains taller and sharper than the Appalachian Mountains in north America?

The Rockies and the Appalachians are similar geologically (although the Appalachians are a little more diverse) however the Appalachians were emplaced a lot longer ago and have been exposed at the surface longer and therefore are more eroded down. By contrast the Rockies are still quite young (they were pushed up roughly in the Cretaceous, probably 100-200 million years after the Appalachians) and haven't been weathered down very much yet.


Why aren't the Appalachian n mountains the tallest in the world?

The Appalachians are a very old mountain range, many millions of year older than the Rockies or the Himalayas. We don't know how tall they were at their tallest, but they have been "wearing down" for millions of years - and that's one reason they aren't the tallest: They are more "worn" than most other ranges.


Which mountain ranges found in the US is heavily eroded?

The Appalachians mountain range is considered to be heavily eroded. They are believed to have been as tall as the Rocky mountains at one time. ++++ The Appalachians are part of the same range as the Scottish Highlands and Norwegian mountains - formed long before the Atlantic Ocean started to open - so are much older than the Rockies and their South American continuation, the Alps and the Himalaya. Consequently they have been in a state of erosion for much longer.
